RESUMEN

BACKGROUND: Patients with atrial fibrillation (AF) and heart failure (HF) have a high risk of thromboembolism and other outcomes and anticoagulation is recommended. HYPOTHESIS: This study was aimed to explore the risk factors associated with HF worsening in patients with AF and HF taking rivaroxaban in Spain. METHODS: Multicenter, prospective, observational study that included adults with AF and chronic HF, receiving rivaroxaban ≥4 months before entering. HF worsening was defined as first hospitalization or emergency visit because of HF exacerbation. RESULTS: A total of 672 patients from 71 Spanish centers were recruited, of whom 658 (97.9%) were included in the safety analysis and 552 (82.1%) in the per protocol analysis. At baseline, mean age was 73.7 ± 10.9 years, 64.9% were male, CHA2 DS2 -VASc was 4.1 ± 1.5, HAS-BLED was 1.6 ± 0.9% and 51.3% had HF with preserved ejection fraction. After 24 months of follow-up, 24.9% of patients developed HF worsening, 11.6% died, 2.9% had a thromboembolic event, 3.1% a major bleeding, 0.5% an intracranial bleeding and no patient had a fatal hemorrhage. Older age, the history of chronic obstructive pulmonary disease, the previous use of vitamin K antagonists, and restrictive or infiltrative cardiomyopathies, were independently associated with HF worsening. Only 6.9% of patients permanently discontinued rivaroxaban treatment. CONCLUSIONS: Approximately one out of four patients with HF and AF treated with rivaroxaban developed a HF worsening episode after 2 years of follow-up. The identification of those factors that increase the risk of HF worsening could be helpful in the comprehensive management of this population.

RESUMEN

BACKGROUND: Heart failure (HF) and atrial fibrillation (AF) are common and coexistent conditions. HYPOTHESIS: To investigate the adverse events and mortality risk factors in patients with AF and HF treated with rivaroxaban in Spain. METHODS: Multicenter, prospective and observational study with a follow-up of 2 years, that included adults, with a diagnosis of nonvalvular AF and chronic HF, anticoagulated with rivaroxaban at least 4 months before being enrolled. RESULTS: A total of 672 patients from 71 Spanish centers were recruited, of whom 658 (97.9%) were included in the safety analysis and 552 (82.1%) in the per protocol analysis. At baseline, the mean age was 73.7 ± 10.9 years, 65.9% were male, 51.3% had HF with preserved ejection fraction and 58.7% were on New York Heart Association functional class II. CHA2 DS2 -VASc was 4.1 ± 1.5. During the follow-up, 11.6% of patients died and around one-quarter of patients were hospitalized or visited the emergency department, being HF worsening/progression the main cause (51.1%), with a 2.9% of thromboembolic events and 2.0% of acute coronary syndromes. Major bleeding occurred in 3.1% of patients, with 0.5% experiencing intracranial bleeding but no fatalities. Compliance with HF treatment was associated with a lower risk of death (hazard ratio: 0.092; 95% confidence interval: 0.03-0.31). CONCLUSIONS: Among patients with HF and AF anticoagulated with rivaroxaban, incidences of thromboembolic or hemorrhagic complications were low. The most important factor for improving survival was compliance with HF drugs, what strengths the need for early treatment with HF disease-modifying therapy and anticoagulation.

RESUMEN

Background: Pulmonary congestion (PC) is associated with an increased risk of hospitalization and death in patients with heart failure (HF). Lung ultrasound is highly sensitive for detecting PC. The aim of this study is to evaluate whether lung ultrasound-guided therapy improves 6-month outcomes in patients with HF. Methods: A randomized, multicenter, single-blind clinical trial in patients discharged after hospitalization for decompensated HF. Participants were assigned 1:1 to receive treatment guided according to the presence of lung ultrasound signs of congestion (semi-quantitative evaluation of B lines and the presence of pleural effusion) versus standard of care (SOC). The primary endpoint was the combination of cardiovascular death, readmission, or emergency department or day hospital visit due to worsening HF at 6 months. In September 2020, after an interim analysis, patient recruitment was stopped. Results: A total of 79 patients were randomized (mean age 81.2 +/− 9 years) and 41 patients (51.8%) showed a left ventricular ejection fraction >50%. The primary endpoint occurred in 11 patients (29.7%) in the SOC group and in 11 patients (26.1%) in the LUS group (log-rank = 0.83). Regarding nonserious adverse events, no significant differences were found. Conclusions: LUS-guided diuretic therapy after hospital discharge due to ADHF did not show any benefit in survival or a need for intravenous diuretics compared with SOC.

RESUMEN

Antecedentes:El antígeno carbohidrato 125 (CA125) ha emergido como un nuevo biomarcador en insuficiencia cardiaca. El objetivo del estudio es determinar si los niveles séricos de CA125 predicen la mortalidad y reingresos totales a un año en pacientes mayores de 70 años e insuficiencia cardiaca aguda (ICA) con fracción de eyección preservada (FEP).Métodos:Estudio observacional prospectivo multicéntrico, que incluyó a 359 pacientes (edad media 81,5 años). La variable de valoración principal fue la mortalidad total por todas las causas y lo reingresos totales por ICA a un año. El análisis de regresión binomial negativa se utilizó para evaluar la asociación entre los valores de CA125 y el pronóstico.Resultados:Al año de seguimiento, se registraron 87 muertes (24,2%). Los pacientes del cuartil inferior de CA125 presentaron una tasa bruta de mortalidad menor (14,4%, 26,7, 26,7 y 29,2; p=0,090). Tras un análisis multivariado, el valor de CA125 se asoció de forma casi lineal y positiva a un mayor riesgo de mortalidad (p=0,009). Dicha asociación fue también positiva pero estadísticamente límite en el caso de los reingresos totales por ICA (p=0,089).Conclusiones:En población mayor de 70 años hospitalizada por ICA con FEP, los niveles elevados de CA125 se asocian a un aumento del riesgo de muerte a un año de seguimiento. La asociación con los reingresos fue más incierta. Los niveles bajos de CA125 identifica un subgrupo de pacientes de bajo riesgo. (AU)


Background:Carbohydrate antigen 125 (CA125) has emerged as a new biomarker in heart failure. The objective of the study is to determine whether serum CA125 levels predict total mortality and readmissions at one year in patients >70 years old with acute heart failure (AHF) and preserved ejection fraction (PEF).Methods:Multicenter prospective observational study, which included 359 patients (mean age 81.5 years). The primary endpoint was total all-cause mortality and total readmissions for AHF at 1 year. A negative binomial regression technique was used to evaluate the association between CA125 and both endpoints.Results:At one year of follow-up, 87 deaths (24.2%) were registered. The patients in the lower quartile of CA125 had a lower crude mortality rate (14.4%, 26.7, 26.7, 29.2; p=0.09). After multivariate analysis, the CA125 value was positively associated with a higher risk (p=0.009). Such association was also positive but borderline significant for the risk of readmissions (p=0.089).Conclusions:In a population older than 70 years hospitalized for AHF with PEF, elevated levels of CA125 are associated with an increased risk of death at one year of follow-up. The association with readmission for AHF was more uncertain. Low levels of CA125 identifies a subgroup at low-risk. (AU)

RESUMEN

IntroducciónLos datos disponibles de las causas de muerte en pacientes ingresados por insuficiencia cardíaca en servicios de medicina interna y en población española según fracción de eyección reducida (FER), preservada (FEP) e intermedia (FEI) son escasos. Su estudio puede mejorar el conocimiento de estos pacientes y su pronóstico.MétodosEstudio de cohortes multicéntrico y prospectivo de 4.144 pacientes que ingresaron por insuficiencia cardíaca en unidades de medicina interna. Se registraron sus características clínicas, tasa de fallecimientos y sus causas agrupadas según FEP (≥ 50%), FEI (40-49%) y FER (<40%) durante una mediana de seguimiento de un año.ResultadosSe registraron 1.198 fallecimientos (29%), de los que 833 fallecieron por causas cardiovasculares (69,5%), fundamentalmente por insuficiencia cardíaca (50%) y por muerte súbita (7,5%) y 365 por causas no cardiovasculares (NoCV) (30,5%), sobre todo por infecciones (13%). La causa más frecuente y temprana en todos los grupos fue la insuficiencia cardíaca. Los pacientes con FEP tenían menor tasa de muerte súbita y mayor de infecciones (p <0,05). Las causas de muerte en FEI fueron más parecidas a las de FEP.ConclusionesLas causas de muerte en pacientes con insuficiencia cardíaca fueron diferentes dependiendo del tipo de fracción de eyección. Los pacientes con FEI y FEP, por su elevada comorbilidad y mayor frecuencia de muerte NoCV, son los que más se beneficiarían de un manejo integral por parte de medicina interna.

RESUMEN

INTRODUCTION: There are few data in the Spanish population about the causes of death in patients admitted to internal medicine departments for heart failure. Their study according to left ventricular ejection fraction (reduced: rEF, mid-range: mEF, and preserved: pEF) could improve the knowledge of patients and their prognosis. METHODS: Prospective multicentre cohort study of 4144 patients admitted with heart failure to internal medicine departments. Their clinical characteristics, mortality rate and causes were classified according to pEF (≥ 50%), mEF (40%-49%) and rEF (<40%). Patients were followed-up for a median of one year. RESULTS: There were 1198 deaths (29%). The cause of death was cardiovascular (CV) in 833 patients (69.5%), mainly heart failure (50%) and sudden cardiac death (7.5%). Non-cardiovascular (NoCV) causes were responsible for 365 deaths (30.5%). The most common NoCV causes were infections (13%). The most frequent and early cause in all groups was heart failure. Patients with pEF, compared to the other groups, had lower risk of sudden cardiac death and higher risk of infections (P <.05). The causes of death in patients with mrEF were closer to those with pEF. CONCLUSIONS: The causes of death in patients with heart failure were different depending on ejection fraction strata. Patients with mEF and pEF, due to their high comorbidity and higher frequency of NoCV death, would require comprehensive management by internal medicine.

RESUMEN

The objective of this study is to determine the prevalence of cognitive impairment (CogI) in patients hospitalized for congestive heart failure, and the influence of CogI on mortality and hospital readmission. This is a multicenter cohort study of patients hospitalized for congestive heart failure enrolled in the RICA registry. The patients were divided into 3 groups according to their Short Portable Mental Status Questionnaire score: 0-3 errors (no CogI or mild CogI), 4-7 (moderate CogI) and 8-10 (severe CogI). A total of 3845 patients with a mean (SD) age of 79 (8.6) years were included; 2038 (53%) were women. A total of 550 (14%) patients had moderate CogI and 76 (2%) had severe CogI. Factors independently associated with severe CogI were age (OR 1.09, 95% CI 1.05-1.14 p < 0.001), male sex (OR 0.57, 95% CI 0.34-0.95, p = 0.031), heart rate (OR 1.01, 95% CI 1.00-1.02, p = 0.004), Charlson index (OR 1.16, 95% CI 1.06-1.27, p = 0.002), and history of stroke (OR 2.67, 95% CI 1.60-4.44, p < 0.001). Severe CogI was associated with higher mortality after one year (HR 3.05, 95% CI 2.25-4.14, p < 0.001). The composite variable of death/hospital readmission was higher in patients with CogI (log rank p < 0.001). Patients with heart failure and severe CogI are older and have a higher comorbidity burden, lower survival, and a higher rate of death or readmission at 1 year, compared to patients with no CogI.

RESUMEN

INTRODUCTION: Acute heart failure (AHF) is a frequent epidemic in geriatrics. The main aim of this study was to evaluate the clinical and prognostic differences of very elderly patients with AHF compared to the rest, and evaluate the factors associated with 90-day mortality. METHODS: We analyzed 3828 patients hospitalized for AHF with an age of ≥ 70 years. The population was divided into three groups: 70-79, 80-89 and ≥ 90 years old (nonagenarians). The baseline characteristics of patients nonagenarians were compared with the rest. In the group of nonagenarians, their clinical characteristics were analyzed according to the left ventricular ejection fraction (LVEF) and the factors associated with mortality at 90 days of follow-up. RESULTS: Nonagenarians showed higher comorbidity and cognitive deterioration, worse basal functional status, and preserved LVEF. Alternatively, they presented a lower rate of diabetes mellitus, lower incidence of de novo AHF, and lower prescription of angiotensin-converting-enzyme inhibitors, aldosterone blockers, anticoagulants, and statins at hospital discharge. Of the total, 334 patients (9.3%) had died by 90 days. The 90-day mortality rate was highest in nonagenarians (7.1% vs 9.8% vs 17%; p = 0.001). Multivariate analysis showed that renal failure, New York Heart Association (NYHA) functional classifications of III-IV, and a more advanced functional deterioration at baseline are predictors of mortality within 90 days. CONCLUSIONS: The AHF in patients nonagenarians has a different clinical profile compared to younger patients and a higher mortality. In this subgroup of patients having a worse baseline functional status, higher NYHA classification (III-IV), and renal failure are predictors of 90-day mortality.

RESUMEN

AIM: Hyponatremia is very often associated with renal disease in patients with heart failure (HF) and, when present, determines a poor outcome. We investigated the role of hyponatremia in HF patients in whom the presence or absence renal insufficiency was accurately predefined. METHODS: This was a cohort study based on the Spanish National Registry on Heart Failure (RICA), a multicenter, prospective registry that enrolls patients admitted for decompensated HF who were subsequently followed up for 1 year. We classified patients into 4 groups according to the presence or absence of renal disease defined by the hematocrit, urea, and gender formula (HUGE) and then according to the presence of hyponatremia (Na ≤135 mEq/L). RESULTS: A total of 3,478 patients were included. Hyponatremia was more prevalent in the group with renal disease (22.1%) than without (18.4%). During admission, both groups with hyponatremia had more complications than those with normal serum sodium. During the 1-year follow-up, patients with hyponatremia and renal disease had a significantly worse outcome (HF mortality and readmission), HR 1.87, 95% CI 1.54-2.29, p < 0.001, compared to those with hyponatremia without renal disease, HR 1.01, 95% CI 0.79-1.3, p = 0.94. CONCLUSIONS: Hyponatremia is more prevalent in patients with renal insufficiency, and outcome is poorest when both renal disease and hyponatremia coexist. Patients with hyponatremia without renal disease show no differences in outcome compared to those without hyponatremia.

RESUMEN

Introducción: La infestación por Strongyloides stercoralis es más prevalente en regiones tropicales, pero existen casos autóctonos en España, principalmente en La Safor (Valencia). Nuestro objetivo era estudiar los casos de un hospital de la provincia de Alicante y conocer si existían casos autóctonos. Procedimiento: Estudio retrospectivo de los casos diagnosticados de estrongiloidiasis en el Hospital Vega Baja (Orihuela, Alicante) entre enero de 1999 y marzo de 2016. Resultados: Se registraron 10 casos, 4 de ellos autóctonos, presentando 2 de ellos un cuadro de hiperinfestación con desenlace fatal. Todos los casos autóctonos fueron en personas ≥69años con síntomas digestivos, cutáneos y/o respiratorios. La serología fue positiva en los 8casos en los que se realizó. En 3 casos se visualizaron larvas en el estudio histopatológico. Conclusiones: Comunicamos los primeros casos autóctonos de estrongiloidiasis en la región Vega Baja. Se deben implantar programas de cribado principalmente en pacientes inmunosuprimidos o en tratamiento corticoideo (AU)


Introduction: Strongyloides stercoralis infection is more prevalent in tropical regions but autochthonous cases have been reported in Spain, mainly in La Safor (Valencia). The objective is to describe the strongyloidiasis cases registered in a regional hospital of Alicante province (Spain) and to determine if they were autochthonous cases. Methods: Retrospective study of all diagnosed cases of strongyloidiasis in Vega Baja Hospital (Orihuela, Alicante) between January 1999 and March 2016. Results: A total of 10 cases were found, four of which were autochthonous cases. Two of them presented with a hyper-infection syndrome, with a fatal outcome. All autochthonous cases were in patients ≥69years old with gastrointestinal, cutaneous, and/or respiratory symptoms. Serology was positive in the 8 cases studied. Larvae were found in histopathological samples of the gastrointestinal tract of three patients. Conclusions: We communicate the first autochthonous cases of strongyloidiasis in the region of Vega Baja. Screening programs should be implemented, especially in immunosuppressed patients or patients under chronic corticosteroid treatment (AU)
